Quick background...My sons father walked out on us in Feb 2013 and moved in with another "woman" the same day. They are still living together. Since this has happened he does see his son on a somewhat regular basis (approx. 12-16 hours a week, with 2 overnights a month). I have been more than civil with him and try to be fair considering the hell he has put us through. This Monday I receive an email TELLING me he is going to Florida in July for a week and is taking my son. I am NOT ok with this. My boy will only be 2 years old, he plans on dragging him around Walt Disney World during the hottest and busiest time of year, and I am very uncomfortable with my son being away from me for a week, especially being over 1000 miles away. This is yet another case of him trying to look good to everyone else, and not thinking about what is best for his son. We do not have a legal custody agreement, but have maintained a pretty set schedule over the last nine months. He is a good father in that he feeds and protects him, but he does not think of his sons best interests and never goes out of his way to spend more time with him or be there when things are tough. I need to know if I am being unreasonable, if I have a right (legal or otherwise) to say no and what I should do. Any advice is appreciated! I just feel like he wants to come off as this Super dad, but he is 't really and truly there for his son at any other time.

You do not have legal right to stop him unless it is ordered by court. If you want more control you should get legal/custody court order. If he is a good father then I dont understand the problem here. mychildcustodycase.com
